Shoulder holster for CCW?

Just curious folks. How many of you carry, or have carried, a CCW weapon in a shoulder holster rig? If so, what is your opinion of them in terms of accessibility, comfort, and concealment?

My own experience with a shoulder rig is somewhat limited, I must admit, but I have carried that way. Personally, I found the method uncomfortable and awkward. I suppose it might have some use if one had to wear a suit coat at all times, but overall, I tend to go with a right hand belt holster carried slightly rearward.

Personally, I have never tried the shoulder holster. I live is a very warm climate, and a jacket year round is not something to look forward to. I am very comfortable in baggy shorts, and baggy shirts, with a .45 on my right hip in a Yaqui style holster. That's if I dress up a little. If I'm out and about in very casual dress, then I am wearing shorts with an elastic waist band and the Smart Carry system.

I have tried several types of holster over the years, as my holster collection will confirm. Of shoulder holsters I have tried two, one sat the gun level with the ground (muzzle pointing to the rear), the other muzzle down. I have not only found them uncomfortable when used for any length of time, but have been very concerned about them being seen (by the wrong guys). I get concerned about my jacket falling open, and the print of the straps, especially in warm weather and light clothing. I still vote FBI (As Pistol has described).

I use a Galco Classic Lite shoulder holster to carry any 1911 style pistol I own. I use it just occasionally since my preferred carry method is strong side OWB, but under a 5.11 covert casual shirt, it is comfortable, easy to access, and easy to adjust for my body type. Also the price is reasonable. I bought it to see how the shoulder holster concept would work for me before I invested in a more expensive model. It works well winter and summer, but since it is only used once in a while, no further purchase is contemplated in this style.

I have three, all a bit different, bought them one after the other and gave up. None of them feel right to me, so I carry behind my right hip in the summer and more forward in the winter with coats.
Maybe there's one that feels right, but I haven't found it yet.

I see no reason for one in any climate. When it's cold I use my 5.11 Tactical Jacket and strap a .45 on the inside velcro of the jacket with a specialized holster. I can remove the jacket and continue on with a social discourse. With a shoulder holster I have to keep the jacket on, and fry like a lobster in public. The shoulder holster idea is dead in my humble opinion.
